The specific embodiment
The utility model building operations climbing scaffold falling proof device, the specific embodiment is:
Contrast Fig. 1, Fig. 2, falling proof device of the present utility model, mainly by compression spring 5, compression spring planet 6, stressed cross bar 9, lever 3, anti-fall pull bar 2 and retaining mechanism 20 are formed, fall arrest pull bar 2 is settled on the supporting roof beam structure 51 that is fixed on the fabric structure 50, retaining mechanism 20 cross-under are on fall arrest pull bar 2, and can on the fall arrest pull bar, lock or unclamp, climbing equipment 40 is jack, it is installed on the climbing equipment force rod 11, scaffold is connected on the climbing equipment 40, and climbing equipment 40 is bearing on the stressed cross bar 9, climbing equipment 40 can be along the climbing equipment force rod upwards or move down, and stressed cross bar 9 can move between strut rail A on the stressed support 8 of climbing equipment and down horizontal B retaining, the stressed support 8 of climbing equipment is fixed on the scaffold crosspiece 7, climbing equipment 40, is driving scaffold and is rising or descend upwards or when moving down along the lifting means force rod.
Contrast Fig. 3, retaining mechanism 20 in the utility model device is mainly by pressing plate 21, return spring 23, guide pillar 24, thimble 30, steel ball 28, steel ball return spring 27, pressing plate 21 and lock body are formed, lock body then is by cylinder 31, post circle 25 and gland 29 are formed, gland 29 is connected the upper end of cylinder 31 by screw, post circle 25 close-fittings are in the outer circumferential sides of cylinder 31, be evenly equipped with three centre holes on the gland 29, the position of cylinder 31 corresponding three centre holes is provided with three inclined holes 26, each centre hole is communicated with corresponding inclined hole 26, return spring 23 places the bottom of inclined hole 26, steel ball 28 is placed on the upper end of return spring 23, thimble 30 is plugged in the centre hole, and its lower end is by touching on steel ball from weight.
Climbing equipment 40 connects retaining mechanism 20 by lever 3, lever 3 is articulated on the support 16 that is connected on the scaffold crosspiece 7, its end is connected (see figure 2) by the upper end of the pressing plate 21 in bolt 13 and the retaining mechanism, and the other end touches the free end that compresses spring 5.Compression spring 5 places on the compression spring planet 6, and compression spring planet 6 is connected with stressed cross bar 9.
Be at climbing equipment and upwards climb or when climbing state downwards, climbing equipment 40 and the scaffold that is connected on this climbing equipment are bearing on the stressed cross bar 9 fully, and stressed cross bar 9 is connected with compression spring planet 6, this undertaking is by the right-hand member effect of the compression spring on the compression spring planet 6 to lever 3, lever 3 rotates around pin joint 4, make its left end to the pressing plate 21 on retaining mechanism 20 tops to pressing down, thimble 30 downward pressing steel balls 28, steel ball 28 along inclined hole 26 to moving away from anti-fall pull bar axis direction, be not pressed on the fall arrest pull bar 2, steel ball return spring 27 is compressed, and retaining mechanism is in releasing orientation.At this moment, climbing equipment drive scaffold climbs on climbing equipment force rod 11 or climbs, and retaining mechanism is inoperative to lifting means and scaffold.
When the upper end of climbing equipment force rod 11 nut 52 (see figure 1)s come off or climbing equipment force rod 11 fracture etc., when making stressed cross bar 9 lose supporting suddenly, scaffold will together fall with climbing equipment force rod 11,6 pairs of lever 3 right-hand members of compression spring on the compression spring planet 6 do not have active force, then the left end of lever 3 is to the pressing plate 21 no downward pressures on retaining mechanism 20 tops, pressing plate 21 will move up under the effect of return spring power 5, this moment, thimble no longer was subjected to the compacting of pressing plate 21, steel ball moves to close anti-fall pull bar axis direction along inclined hole under the effect of steel ball return spring, make steel ball be locked on the fall arrest pull bar, and the fall arrest pull bar is fixed, so whole falling proof device can only move up, can not move down, play the fall arrest effect in the scaffold lifting process, i.e. locking state.Like this, retaining mechanism 20 just can effectively prevent climbing equipment and the falling of the scaffold that is attached thereto, and connection system for guide rail firmly is locked on the fall arrest bar.
